Co-produced by Ekta Kapoor and Shobha Kapoor, "Once Upon A Time In Mumbaai 2" is a sequel to the 2010 movie "Once Upon A Time In Mumbaai" and also stars Akshay Kumar, Sonakshi Sinha and Sonali Bendre in lead roles.

"We have been shooting 12-hour shifts every day, all month, without a single off. As a result, I have had to bring my trainer on the set to work out in between shots. We have also built a space for dance rehearsals," Imran said in a statement.

Imran is also shooting for "Gori Tere Pyaar Mein".
